You would have to change the code to suit your needs. The Tutorial is just a starting point for you to get the navbar set you. You would have to place the links and manually edit the code to suit your needs.

At the top you'll see a object name dropDown. To the left of the colon is the URL of the link you want to modify ( just the path not the whole URL ), and to the right of the colon is the HTML for your dropdown. I have some examples for the inbox and edit profile.

@Ange Tuteur Problem i'm having is getting the links to work as shown this is the link for the service button /f6-market-place then in the drop down there should be "COD Services" /f72-call-of-duty-series "GTA Services" /f103-grand-theft-auto-v-services and last "Private CID" /t3994-service-ps3-unban-service-1st-private-cid-seller I must be doning something wron i cant even get the script to attach to the services button
